Enable the  DHCP filter, buy a book on ISA and read it, explore 
www.isaserver.org.

        Hi
        
        
        We got an Isaserver running with two nics one for the internal network
        and one for the external network.
        The external nic must use dhcp to obtain an ip address else it does not
        work with the ISP however ofcourse our ip address is always the same
        cause it is bound to the external nic mac address by the ISP.
        When we start the system everthink work fine but after six ours the dhcp
        lease has ended and the nic can`t obtain a new ip address.
        So we contacted the ISP and they said that there was a discovery for an
        dhcp server but never an acknownledge.
        When we dissable the packet filter everything worked fine we always can
        obtain an new ip address but ofcourse that is not what we wan`t.
        Do i have to create an packet filter for the external interface ? Cause
        i did create some packet filters but all with no succes.
        Or do i always need a static ip address ?
        
        Please Help Me
